Decent Cheapish Firewall?

[Ryan0r]

A router is only as good as its setup. If it's sitting merrily letting everything through (and on standard ports), you're not terribly protected. False sense of (internet) security

Kaspersky Internet Security gets my vote. AV + software firewall.

The point here is distinguishing the roles you want a firewall to play. Do you only care about preventing intrusions onto your network, or do you want to restrict which software on your PC can access the internet? Because a NAT router is fine for the former, but it won't do anything for the latter, which is where a software firewall comes in. Whether or not you think they're worthwhile is up to you - personally I don't use one - but they most definitely have a point.

Spot on.

To the OP Kaspersky Internet security as mentioned by other posters would probably be your best bet.
